BUFFING-ROLL.

To all whom 2'25 may concern:

Be it known that'I, JOSEPH L. SMALL, a

citizenof the United States, residing at improvements in bu fling rolls and the pfincipal object of the invention is to provide a butling roll which is particularly adapted for use for buffing tin plates.

Another object of the invention is to pro 'vide a bufiing roll which is composed of a plurality of scraps of fabric so as to effect a considerable saving in the manufacture of wheels of this type.

A further object of the inventionis toprovide a wheel in which the fabric scraps are firmly attached together by a suitable nonorganic adhesive'which when the wheel is rapidly rotated. against the material being buffed becomes slightly softened so that the polishing material instead of being-rubbed or brushed from the surface of the metal being polished will be gathered and held by the wheel or roll.

Still another object of the invention is to provide a roll which may be pressed together so that the rollwill be of equal density throughout thereby insuring the proper polishing operation of the device throughout its entire length. Still another object of the invention is to provide a roll which may be pressed into forming a suitable mold by the'placin of the scrap in the mold and the coating 0 adjacent spaces with a suitable wax or waxes and pressing the whole so as to form a mass of equal density which when operated under working conditions willleave no undesirable and objectionable deposit on the surface of the material.

A still further object of the invention is to provide a process for using the scrap and waste out from bufiing rolls used in the ordinary manner.

As another object the invention con'ipre hends the use of such scrap for manufactur ing the rolls thereby materially reducing the cost of production.

With these and other objects in view, the

It will be unbe understood that in forming the mass suitderstood that in thepressing operation various degrees of density of] the roll may be had according to the amount of pressure applied and .thus bufling rolls for various purposes may be made. From the foregoing it will'be apparent that a roll is provided. which may be constructed of scraps of fabric securedtogether by a suitable adhesive material which when heated by the friction generated by the rapid rotation of the roll becomes slightly softened so that the polishing material" placed on the surface of the plate will be gathered by the roll rather than brushed from the surface of thearticle being p ol-,
